Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and decrease inflammation [1]. According to the manufacturer's website, the recommended adult dose of Advil is one or two tablets every four to six hours, as needed, up to a maximum of six tablets in 24 hours [3]. It is important to follow the dosing instructions on the label and not exceed the recommended dose, as this can increase the risk of side effects, including stomach bleeding, kidney damage, and heart attack [2].

The USA Today article states that while Advil is generally safe for occasional use, taking it too often or in large doses can cause serious health problems. It is recommended to speak with a doctor before taking Advil regularly, especially if you have a history of stomach ulcers, heart disease, or kidney problems [2]. Additionally, the Drug Patent Watch website lists several patents for Advil, indicating that the drug has been on the market for many years and is widely used [1].

In summary, Advil can be taken every four to six hours as needed, up to a maximum of six tablets in 24 hours, but it is important to follow the dosing instructions on the label and not exceed the recommended dose. It is also recommended to speak with a doctor before taking Advil regularly, especially if you have a history of certain health problems. Advil has been on the market for many years and is widely used for pain relief and reducing fever and inflammation.
